  • Patent number: 6419780
    Abstract: A method for manufacturing laminated shingles achieves heretofore unobtained versatility by employing separate rolls of substrate materials for underlayment and overlayment webs of the laminated shingles being made. The method contemplates that each of the underlayment and overlayment webs are separately coated with an asphalt composition and granule formulation, whereby the asphalt compositions and/or granule formulations and patterns can be different for each of the webs. Each of the webs is subdivided into plural web portions, which are thereafter laminated, and transversely cut for formation of individual laminated shingles. Laminated shingles formed in accordance with the present method may comprise underlayment and overlayment substrates which differ in thickness, with differing asphalt compositions applied thereto, and/or different granule color formulations and patterns applied to the underlayment and overlayment.
